Japan Telecommunications Services Forecast, 2025–2029

This IDC study provides market forecasts and outlook for the Japan telecommunications services market from 2025 to 2029. The Japan telecommunications service market in 2024 was expected to see an increase in traffic because of increased cloud connections and expanding investment in Internet of Things (IoT) and to become increasingly mature. In addition, within the enterprise segment, private network lines, which are often used as access connections from branch offices, are expected to remain flat or decline slightly, while public cloud connection lines, internet connections for offloading traffic, IoT lines, and Ethernet dedicated lines, which are often used for connections between DCs, are expected to show steady growth."Market trends are also reflecting the ongoing structural changes in enterprise WANs due to the advancement of cloud computing and digital transformation (DX). Telecommunications carriers and systems integrators (SI providers) should offer new integrated services based on software-defined networks (SDNs) that combine zero trust security with a variety of access connections, including the internet and mobile," says Yoko Ono, research manager, Infrastructure and Devices, IDC Japan.This is the English translation of the Japanese document IDC #JPJ52161825.
